Hotels: How do I request a link to the hotel payment system for a guest to pay before checking in?

At the moment, Booking.com does not allow you to automatically pay in advance, so you have to contact the hotel directly.

To do this you will need to find the "Booking details" section in the booking confirmation email, where you will find the hotel phone number and there will also be a link for contacting the hotel by email:

In the request, you will need to specify the reservation number and the hotel will provide you with all the necessary information on how to proceed. If you have any difficulties in solving this issue, you can always contact us at support@appintheair.com.
